A new YouTube video appears to show a baby clapping along to its parents singing during an ultrasound.
The video's uploader, Jen Cardinal, said that she and her husband noticed their baby clapping during its 14-week ultrasound. Her husband grabbed a camera and began filming the baby clapping as Cardinal and her doctor sang "If You're Happy and You Know It" out of frame. The clip, which is most likely cleverly edited for enhancement, soon went viral.
"At our 14 week ultrasound our baby was clapping, so I sang a song with our doctor as my husband filmed," Cardinal wrote in the video description.
